ADJUSTABLE BEARING.

SPECIFICATION forming part of Letters Patent No. 618,854, dated.February 7, 1899.

Application filed October 27, 1897. Serial No. 656,519. (No model.)

To a whom it may concern:

Be it known that I, OHAUNOEY N. DUTTON, of the city, county, and Stateof New York, have invented a certain new and useful Improvement inAdjustable Bearings, of which improvement the following is aspecification.

My invention relates more particularly to bearings for the shafts ofretaining-wheels employed in the connection of one comparatively largeand heavy body to another, with the capacity of a limited degree ofrelative movement under rolling friction, as exemplified in the meansfor connecting an aqueduct and lock which are set forth in anapplication for Letters Patent for improvement in aqueducts filed by meOctober 7, 1897, Serial No. 654,341. My present invention is, however,not limited to such specific application, but may be utilized withoutchange of structural or operative principle in the bearings of wheels ofother constructions or mechanlsms.

The object of my invention is to provide a shaft-bearing by means ofwhich the slipping of the wheel from operative contact with the memberon which it bears will be rendered impossible without rupture of thesupporting-frame and all probable ranges of adj ustment shall beeffectually provided for.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a horizontal central sectionthrough an adjustable bearing, illustrating an application of myinvention; Fig. 2, a side view in elevation with the wheel removed;Figs. 3 and 4, horizontal sections through an adjustable bearing inwhich the bearing-block and distancedolock are formed integral with thebearing-sleeve, the shaft being shown in line with the axis of thebearing and at angle thereto, respectively; and Fig. 5, a side view inelevation.

In the practice of my invention the bearing is mounted and supported inasuitable frame, which in this instance is shown as formed of twoangle-bars l 1, which are bent into U form and surround the hearing ateach end thereof, said bars being connected by plates.

2 2 above and below the horizontal axial plane of the shaft, so as toform a stiff bearinghead. Housing-blocks 3 4 are fixed in each of theframe-bars 1 1, and the inner faces 5 of the housing-blocks or thosenext the shaft are turned out curvilinearly or in the form of a surfaceof revolution about an axis transverse to the bearing frame and shaft,preferably a cylindrical surface.

The shaft 7, upon which the wheel 6 is suitably secured,is journaled ina bearing bushing or sleeve 8, which is made in two parts, said sleevefitting between a shoulder on the wheel and a collar 7 a on the shaft.When the bearing-sleeve is placed upon the axle, it is lined to aneasy-running fit, and a bearingblock 9, which is made in two parts andbored to fit the bearing-sleeve 8, is bolted about said sleeve and theshaft 7 and lined thereon, so that the shaft may turn without unduefriction and at the same time be free from slackness or lost motion. Thetwo sections of the bearing-block fit closely between the plates 2 2 ofthe frame, which are faced to receive and fit the sections of thebearing-block. After the wheel is secured upon the shaft and thebearing-sleeve and bearing-block fitted upon the shaft the shaft,together with the sleeve and block, is pushed into the space between theplates 2 2.

The shaft 7 is adjusted so that the wheel 6 I shall run truly in desiredposition or relation to the working parts which function with it byadjustable main gibs 11 and backin -gibs 12, which are fitted betweenthe curvilinear bearing-faces 5 of the housing-blocks 3 4 and the sidesof the bearing-block 9 at each end thereof. The gibs 11 and 12, whichare provided to perform the functions of wedging members, are disposedin pairs on each side of the shaft, the outer or main gibs 11 havingtheir outer faces curved conformably with the bearingfaces 5 of thehousing-blocks 3 4 and their inner faces inclined to the vertical axialplane of the bearing. The inner or backing gibs 12 have their outerfaces inclined correspondingly with the adjacent faces of the main gibs11, and their inner faces, which abut against the sides of the sectionsof the bearing-block 9, are parallel with the vertical axial plane ofthe bearing, so that the gibs 11 may adjust against thehousing-blocks,with the angles in cluded between them and the sides ofthe bearing-block equal to the angle of the backing-gibs 12, and thatthe latter may fit tightly between the main gibs and the bearing-blockand wedge all the parts together.

Lateral projections or distance-blocks 1O 10 are shown in Fig. 1 as madeseparate from and fitting in lateral recesses in the sections of thebearing-block 9 and as connected thereto by bolts 10,while in Figs. 3and 4 theyare formed integral with the bearing-block and bearingbushingsections. For the purpose of preventing the gibs 11 and 12 from backingout or loosening the ends of the distance-blocks are inclined relativelyto a vertical transverse plane of the bearing, and supplemental gibs 1112 are respectively interposed between the inclined ends of thedistance-blocks and the adjacent vertical ends of the gibs 11 12.

In assembling the parts the bearing-sleeve and bearing-block areadjusted upon the shaft and inserted with the shaft in the frame betweenthe plates 2 2 and the housing-blocks 3 4, and the shaft is adjusted sothat the wheel may run in proper relation to the member on which itbears by carefully adjusting and tapping the several members of the fourpairs of gibs 11 12, so that all their contact-faces come to a properbearing, any misalinement being taken up by adjusting the gibs one uponanother, as shown in Figs. 3 and 4, which illustrate the shaft as in andout of line, respectively, with the axis of the bearing. After theprimary gibs are in position and driven home to a perfect bearing thedistance-blocks 10, if made separate from the bearing-block sections,are secured thereto by the bolts 10, and the supplemental gibs 11 12 areinserted and driven to a bearing between the ends of the distance-blocksand the adjacent faces of the respective primary gibs and may besecured, if considered necessary or desirable, in any of the ordinaryways well-known to mechanics. the gibs 11 12 in adjusted position-as,for example, straight liners made a tight fit by bolts or screwsmay beemployed if preferred.

It will be seen that it is impossible for the wheel to slip from itsnormal bearing on the member with which it makes operative contact solong as the frame, which is of course made of proper strength, remainsintact and also that adjustment within any probable range and directionis provided for. It is also obvious that if greater range of adjustmentbe desired it is only necessary to provide new gibs of proper form.

I claim-as my invention and desire to secure by Letters Patent Any otherknown means of holding 1. The combination, substantially as set forth,of a supporting-frame, having two pairs of opposite curvilinearlyturnedbearingfaces, a bearing-block fitting in said frame, a shaft j ournaledin said bearing-block, adj ustable main gibs interposed between thesides of the bearing-block and the curvilinearlyturned bearing-faces, ateach end of the bearing-block, and backing-gibs interposed between theadj ustable main gibs and the bear ing-block.

2. The combination, substantially as set forth, of a supporting-frame,having two pairs of opposite curvilinearly turned bearingfaces, abearing-block fitting in said frame, a shaft journaled in saidbearing-block, and pairs of gibs interposed between the sides of thebearing block and the curvilinearlyturned bearing-faces, at each end ofthe bearing-block, the members of said pairs abutting by inclined faces,and the outer members having faces curved conformably with thebearing-faces of the frame.

3. The combination, substantially as set forth, of a supporting-framecomposed of side bars and connecting-plates, housing-blocks fixed to theframe-bars and having curvilinearly-turned bearing-faces, abearing-block supported between the frame-plates and between saidbearing-faces, a shaft journaled in said bearing-block, pairs of gibsinterposed between the sides of the bearing-block and the bearing-facesof the housing-blocks, at each end of the bearing-block, the members ofsaid pairs abutting by inclined faces, and

the outer members having faces curved oonformably with the bearing-facesof the housing-blocks, and retaining devices for holding said gibs inadjusted position.

4. The combination, substantially as set forth, of a supporting-frame,having curvilinearly-turned bearing-faces,a bearin g-bloclc fitted insaid frame, a shaft journaled in said bearing-block, pairs of main gibsinterposed between the sides of the bearing-block and thecurvilinearly-turned bearing-faces, at each end of the bearing-block,the members of said pairs abutting by inclined faces,and pairs ofsupplemental gibs, each member of which is interposed between one of themain gibs and an inclined end face on a lateral projection on thebearing-block.
